简便运算过程如下:
103x12
=(100+3)x(10+2)
=100x10+100x2+3x10+3x2
=1000+200+30+6
=1200+30+6
=1230+6
=1236
这道题可以简便计算,运用四则运算法则,先将103拆分成100+3,再分别乘以12,再将乘积相加即可。解题思路如下:103*12=(100+3)*12=100*12+3*12=1200+36=1236 谢谢
计算如下:
103×12
=103×(10+2)
=103×10+103×2
=1030+206
=1236
103×12简便运算
103×12
=(100+3)×12
=100×12+3×12
=1200+36
=1236
103×12简便运算?
103×12=103x3x4=412x3=1236
